Baldwin 5066055IDM – Frequently Asked Questions
1) What is a half dummy knob, and does the Baldwin Estate 5066 actually latch?
A half dummy is trim only. The Baldwin Estate 5066 with 5078 rose is a dummy function knob, non-keyed, with no latch and no turning mechanism. It surface mounts to one face of the door and gives you something to pull on, which is what you want on a closet door, a false door leaf, or the inactive leaf of a pair. If you need the door to stay shut or to operate a latchbolt, you need a passage, privacy, or entry function instead.
2) Will the Baldwin 5066 knob work on a 1-3/8 inch door as well as a 1-3/4 inch door?
Both. The 5066 knob with 5078 rose works on 1-3/8 inch and 1-3/4 inch thick doors, which covers standard interior residential doors and the heavier 1-3/4 inch leaf.
3) I'm doing a whole house in Baldwin Estate 5066 knobs. Can I match the dummy doors to the passage and privacy doors?
Yes. The 5066 knob is offered as a complete passage, privacy, full dummy or half dummy set in Baldwin's Quick Ship program, so the closet and false doors can carry the same knob and 5078 rose as the operating doors. Note that Quick Ship passage and privacy sets are built on a 2-3/8 inch backset latch only; the 5066 knob itself is catalogued for 2-3/8 or 2-3/4 inch backsets, so a 2-3/4 inch bore falls outside the Quick Ship latch.
4) My door is already bored for a knob. Will the Baldwin 5066 cover the existing prep?
The 5066 series prep uses a 1 inch edge bore and a 2-3/8 or 2-3/4 inch backset, which is the standard residential cylindrical prep. As a half dummy there is no latch going into the edge bore, so the knob mounts to the face of the door and the 5078 rose covers the cross bore. If you are pulling an old knob off, the existing face bore will be hidden as long as it is a standard 2-1/8 inch cylindrical bore.
5) What is a comparable single dummy knob to the Baldwin Estate 5066 for a commercial-grade opening?
The Baldwin Estate 5066 half dummy knob with 5078 rose is a residential dummy trim in the Estate Series. If the job calls for a commercially graded dummy instead, the Schlage A170 is a single dummy trim rated ANSI/BHMA Grade 2, heavy duty, in the A Series, and the BEST 6K Series single dummy trim is a Grade 2 medium duty dummy knob. Both are non-keyed dummy trim like the 5066, so they mount to the door face without a latch.
6) I need a dummy knob for both sides of a double door, not just one side. What should I order?
The Baldwin Estate 5066 with 5078 rose is a half dummy, meaning one knob for one face of the door. For both faces, dummy pairs include the Emtek Arts and Crafts Hammered Egg dummy knobset sold as a pair, the Emtek Classic Brass Crystal Georgetown dummy pair, and the Emtek Providence crystal dummy pair. Each of those ships two knobs per set for an inactive door leaf.
7) The door actually latches - what should I use instead of the Baldwin 5066 half dummy?
The Baldwin Estate 5066 is dummy function, so it has no latch and does not operate. For a latching hall or closet door, passage knobsets include the Dexter C2000 Grade 2 passage cylindrical ball knob, the Corbin Russwin CK4410 Grade 2 passage/closet knob, and the Schlage D10S Grade 1 heavy duty passage latch with Orbit knob. For a bed or bath door, the Dexter C2000 Grade 2 privacy knob or the Pamex FTF Baron Grade 3 privacy knob covers the thumbturn function.
8) Do I need to worry about handing when ordering the Baldwin Estate 5066 half dummy?
No. The 5066 is reversible, so the same part works on a left or right hand door. Order by finish, not by hand.
9) I need knobs on both sides of a closet door that doesn't latch. Is the half dummy the right call?
One half dummy covers one face only. For knobs on both faces you either order two half dummies or go to a full dummy set. Baldwin offers the 5066 knob in a full dummy configuration as well as half dummy. If you want it supplied as a pair out of the box, Emtek's Hammered Egg, Georgetown and Providence dummy knobsets ship two knobs per set.
10) Which knobs look like a substitute for the Baldwin Estate 5066 half dummy but are not?
Several knobs share the round trim look without sharing the function. The Cal-Royal BA40 and Bravura Biloxi are true dummy function and do substitute. The Omnia 434/PA egg knob latchset is passage function, and the Kwikset 200P Polo ships with a 6AL latch and round corner strike, so both bore and latch the door rather than surface-mounting. Exit device trims such as the Sargent 28C-KNOB and the Sargent 78-2875 outside knob are built for panic hardware, not a bored door prep. The Baldwin Estate 5066 is non-keyed dummy trim with a 1 inch edge bore listed for the matching bored set.
11) What dummy knob should I use on doors thicker than the Baldwin Estate 5066 covers?
The Baldwin Estate 5066 half dummy knob is stated for 1-3/8 inch and 1-3/4 inch thick doors. For thicker leaves, the Schlage A170 single dummy trim covers 1-3/8 to 1-7/8 inch. If the opening needs an operating knob rather than dummy trim at greater thickness, the Corbin Russwin CK4310 Grade 1 passage knob and the Falcon X101 Grade 1 passage knobset cover 1-3/8 to 2 inch and 1-3/8 to 2-1/4 inch respectively.
12) I am standardizing knobs across a building and need a keyed version to match the Baldwin Estate 5066 style. What are the options?
The Baldwin Estate 5066 is non-keyed dummy trim, so keying is handled by a separate lockset. Keyed round-knob options include the Cal-Royal BER00 Grade 3 entrance/office knob with a Kwikset keyway, the Kwikset 400P-CP Polo keyed entry knob rated Grade 3 for 1-3/8 to 1-3/4 inch doors, and for commercial keying the Corbin Russwin CK4851 entrance/office knob with a conventional cylinder or the Sargent 8XG04 Grade 1 storeroom knob with a 2-3/4 inch backset.
13) Does any comparable knob to the Baldwin Estate 5066 carry a fire rating?
The Baldwin Estate 5066 half dummy knob is a residential Estate Series trim. Where a fire-rated opening is involved, the Falcon W101 Grade 2 medium duty passage knob and the Falcon X101 Grade 1 heavy duty passage knobset are both listed as fire rated. Note those are latching passage knobs, not dummy trim, so they change the function at the door.
14) Can I mix the Baldwin 5066 knob with levers or different rose styles on other doors?
Yes. Baldwin's Estate line is built to be mixed: the 5066 knob can be combined with levers and a range of roses across passage and privacy sets, and the same trim family extends to mortise sets using handleset trim or escutcheon plates. That lets you keep one finish through a house while varying the handle style room to room.
15) For a multi-unit job, is there a knob sold in bulk instead of single pieces like the Baldwin Estate 5066?
The Baldwin Estate 5066 half dummy is sold as an individual knob, and Baldwin knobs and roses can be mixed to build passage, privacy, full dummy or half dummy sets. For volume work on identical doors, the Sure-Loc Bergen round knob comes as a 6-pack with adjustable backset, and the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for 1-3/8 to 1-3/4 inch doors.
16) How does the Baldwin Estate 5066 compare with the Cal-Royal BA40 dummy knob?
Both are dummy function knobs with no latch. The Baldwin Estate 5066 pairs with the 5078 round rose in the Estate Series and is listed for 1-3/8 inch and 1-3/4 inch doors with a reversible hand. The Cal-Royal BA40 is a dummy knob in the Barrington BA Series covering a 1-3/8 to 1-3/4 inch door thickness range.
